Shada by Gareth Roberts

It’s appropriate that so much of Shada is concerned with the power and significance of an ancient book, as Douglas Adams’ original has itself become a kind of palimpsest, with layer upon layer of new material being added but with the original material still visible underneath. Over the years since the television production was scrapped partway through filming, there have been a number of attempts to complete the work, all of them adding new material, until what we understand when people discuss Shada is so much more than the 70 minutes or so of footage that was actually completed.
